Thanks for all your help guys, here is what I have done so far

1 - a check-hosts script that uses a host-list.txt to ping konwn hosts

./check-hosts (script that pings hosts and generates the ping-results.txt)
rm -f ping-results.txt
cat hosts-list.txt |\
while read line
do
echo . >> ping-results.txt
date >> ping-results.txt
ping -c 5 -q $line >> ping-results.txt
echo $line
done

2 - host-list.txt

Host11
Host12
Host13
Host14

3 - I have modified the awk script (named extract-sla) from Zaxxon's response to read like this

awk '
/^PING / {h=$2}
/packet loss/ {pl=$6}
/min\/avg\/max/ {
split($4,a,"/")
printf("%s %s %s %s\n", h, a[2], a[4], pl )
}
' ping-results.txt

4 - Here is the new output from the results (which I can store into a file)

Host11 56.817 8.520 0%
Host12 55.031 8.485 0%
Host13 72.351 40.053 0%
Host14 32.590 9.705 0%

** Is there a way to get rid of the % sign since we already know it's a percentage.

5 - I would like to input these numbers into a database with a mysql command (the database and tables are already created)

Hostxx a b c

mysql -h 10.255.1.11 -u ping --password='ping' -D host_SLA -e "UPDATE device_list SET latency=a, jitter=b, loss=c WHERE host='Hostxx'";


Thanks for all your responses
